PHOTOPRINTING-MACHINE.

Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed September 23., 1916. Serial No. 121,778.

To all whom it may concern:

Be it known that I, FRANK L. STUBER, a citizen of the United States, residing at South Bethlehem, in the county of Northampton and State of Pennsylvania, have invented new and useful Improvements in Photoprinting-Machines, of which the following is a specification.

This invention relates to devices especially adapted to be used for printing photographs and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a photographic printer adapted to be manipulated to extend. or increase the printing operation at desired areas of the print and negative thus bringing out features and parts of the print which might otherwise be obscure if the entire surface of the print was subjected to the same time exposure.

With this object in view the device includes a casing having a frame pivotally mounted therein. Two electric lights are provided, one located within the casing and the other above the same and the wires which are arranged to transmit the current to the said lights are provided with push buttons located in the path of movement of a pin carried by the frame. Consequently when the frame is in one position and the said pin encounters one of the said push buttons one of the lights is illuminated while the other is not and when the frame is swung so that the pin encounters the other push button the second mentioned light or bulb is illuminated and at the same time the current is interrupted to the first mentioned light which goes out. Catches are mounted upon the casing and are engageable with the lug mounted upon the frame whereby the frame is held at the position to which it is turned. A clock mechanism is connected with the casing and a releasing device is connected with the said clock mechanism whereby one of the said catch devices may be moved to release the frame and the frame under the tension of the spring which actuates the push button is turned slightly so that the pin is moved away from the push button and the said push button assumes an open position thus interrupting the current to the light and thereby providing automatic mean-s for cutting off the light when the print has been subjected to the same for a predetermined length of time.

In the accompanying drawing Figure 1 is a side elevation of the printing device;

Fig. 2 is a top plan view of the same;

Fig. 3 is a longitudinal sectional view of the same;

Fig. -l is an end view of the same;

Fig. is a fragmentary sectional view of the same cut on the line 5- 5 of Fig. t:

Fig. 6 is a similar view out on the line 66 of Fig. 2;

Fig. 7 is a fragmentary perspective view of parts of the same;

Fig. 8 is a sectional view of a push button used on the same.

The photographic printing device comprises a casing 1, which may be made of wood or any other suitable material. An electric bulb 2 is located in the casing l and wires 3 are connected with the bulb 2 and a push button 4: of usual pattern is mounted in the casing 1 and connected with one of the wires 3. hen the button at is closed the said wires 3 are adapted to trans mit the current to the bulb 2 whereby the same is illuminated.

A standard 5 is pivotally mounted in a socket member 5 upon the casing 1 and carries at its upper end a bulb 6. Wires 7 are connected with the bulb 6 and also one of the said wires 7 is connected with a push button 8 mounted in the casing 1.

A printing frame 9 is pivotally mounted in the top of the casing 1 and the said frame carries a. presser board 10 which is preferably made in three sections and which is held in a closed position with relation to the frame 9 in the usual manner. A pin 11 is carried at one end of the frame 9 and the push buttons 4 and 8 are located in the path of movement of the said pin. Spring pressed catches 12 and 13 are mounted upon the casing 1 and the frame 9 carries a lug 14 which is adapted to engage under the said catches at different times whereby the frame 9 is held at the position to which it is turned.

A clock 15 is mounted upon the casing 1 and is of the usual form of alarm clock. A lever 16 is pivoted upon the casing 1 and may be encountered by the clapper or key of the clock when the said clapper sounds the alarm thus the clapper or any other movable part of the clock may be used for swinging the lever 16. I

A lever 17 is pivoted at one'end of the casing 1 and the free end of the lever 16 lies transversely across the free end portion of the lever 17'. The intermediate portion of the lever 17 lies upon a lug 18 provided upon the catch 13.

The printing of the photograph is accom: plished in the following manner. The sensitized paper and the negative are placed in the frame 9 in the usual manner and the said frame is turned whereby the lug 1a is caught under the catch member 12. This moves the pin 11 in contact with the push button 4 and consequently the bulb 2 in the casing 1 is illuminated. The light from the said bulb starts the printing upon the sensitized paper. When the operator determines that the proper shading of the print has been accomplished he depresses the catch device 12 wher by the lug let is released and the frame 9 is then swung so that the lug 1a is under the catch device 13. This removes the pin 11 from the push button 4 and the said button automatically assumes an open position and the passage of the current along the wires 3 to the bulb 2 is interrupted. At the same time the pin 11 is brought into contact with the push button 8 which is closed and the electric current passes along the wires 7 to the bulb 6 which is illuminated. Thus the exposed negative and paper are brought under the bulb 6 and are subjected to the rays of light coming therefrom.

The operator may then set the clock device 15 so that its clapper will operate at any desired future time and the printing apparatus requires no further attention. At the expiration of the time the clapper or the other removable parts strikes the lever 16 whereby the same is swung and the said lever in turn swings the lever 17 which is in engagement with the lug 18 upon the catch device 13. The said lever 17 swings the catch device 13 from the lug 14: and the tension of the spring of the push button 8 comes into play whereby the pin 11 is moved in an upward direction and the frame 9 is turned slightly. In consequence of this movement on the part of the pushbutton 8 electric circuit along the wires 7 is interrupted and the light at the bulb 6 goes out.

The standard 5 carries a laterally disposed finger 19 and a pin 20 is mounted on the casing 1 in the path of movement of the said finger. A spring 21 engages the stand ard 5 and the casing 1 and is under tension with a tendency to normally hold the finger 19 in engagement with the pin. When the said finger is in contact with the said pin the bulb 6 is directly above the intermediate portion of the frame 9 as best shown in Fig. 2 of the drawing. One of the pivot pins of the frame 9 is provided with a laterally disposed extension 22 which is adapted to en- Gopies of this patent may he obtained for counter the linger 19 when the frame 9 is turned in the casing 1. Thus during the turning of the said frame the standard 5 is swung whereby the bulb 6 is carried from over the frame to the position shown in dotted lines in Fig. 2, and hence the said bulb is not in the way of the operator during the final printing of the photograph. hen the frame 9 is swung back the spring 21 returns the standard 5 and the parts mounted thereon to their normal positions.

A lens 28 is mounted on the standarc 5 below the bulb 6 and may be used to concentrate the rays of light from the said bulb to increase the printing at any particular spot on the picture.

From the foregoing description taken in connection with the accompanying drawing it will be seen that a photograph printing apparatus of simple form is provided that the same may be readily manii'nilatcd to in tensify or increase the printing operation at certain areas of the paper and to retard or diminish the printing operation at other areas thereof thus n'iaking it possible to bring out in the same print the features which otherwise might be clouded or obscure if the entire area were subjected. to the same time exposure and the same intensity of light.

Having described the invention what is claimed is 1. A photographic printing device comprising a casing, lighting means located one within the casing and another above the same, a frame pivotally mounted in the easing and having a sectional presser board means for holding the opening of the frame toward one or the other of the lighting means and means carried by the frame and adapted to operate the lighting means whereby the lighting means toward which the opening of the frame is disposed is illuminatcd.

2. A photograph printer comprising a casing, lighting means located one within the casing and the other above the same, a frame pivotally mounted in the casing and having a sectional presser board, catch devices for holding the opening in the frame disposed toward one or the other of the lighting means means carried by the frame and adapted to engage the lighting means whereby that lighting means to which the opening in the frame is disposed is illuminated, a catch mechanism for holding the frame the position to which it is swung, a. timing device located adjacentthe casing and means mounted upon the casing and adapted to be operated by the timing device for releasing the catch device.

In testimony whereof I my signature.
